Obviously each of the races in Lausanne this weekend look great (WR watch in the M800, anyone?) but the W800 looks very interesting. Feels like a good preview of worlds. Unfortunate that Wiley won't be in Tokyo but I hope she can run a good PR here.
I think there is a real chance we see a 1:53 this weekend if the weather cooperates. Lausanne is usually very fast and Keely is obviously in great shape.
